W hat I claim as my invention and desire to secure by Letters Patentis 1. In a carbureter the con'ibination of, an air valve, a mixing orcombining chamber therein for fuel and air, conduits between saidchamber and supplies of fuel and air respectively, an outlet from saidchamber, a

flattened or exleruled end portion on the valve into which said outletopens, a disk arranged substantiallyparallel to and close to theflattened or extended portion of the valve and means to adjust the diskrelatively to the flattened or extended portion of the valve.

2. In. a carbureter the combination of, an air valve, a mixing orcombining chamber therein for fuel. and air, conduitsbetween saidchamber and supplies of fuel and airrcspectively, an outlet from saidchamber, a flattened or extended end portion. on the valve into whichsaid outlet opens, a disk arranged substantially parallel to and closeto the flattened or extended portion of the valve, and aspreading meansarranged on the disk on that side adjacent the outlet.

3. In a carburetor the combination of, an air valve, a mixing orcombining chamber therein "for fuel and conduits between said chamberandsup lies of fuel and air respectively, an outlet from said chamber, aflattened or extended end portion on the valve into which said outletopens, a disk arranged substantially parallel to and close to theflattened or extended portion of the mosses valve, means to adjust thedisk relatively to the flattened or extended portion of the ,valve, anda spreading means arranged on the disk on that side adjacent the outlet.

' 4-. In a carbureter the combination of, an air valve, a mixing orcombining chamber therein for fuel and air, conduits between saidchamber and supplies of fuel and air respectively, an outlet from said.chamber,;a

head in connection with a "hollow cylindrical portion, a disk adjacentthe flattened end,

spacing members between the disk and-said valve-head with means tosecure said disk to the flattened or extended head, a fuel cellduitdisposed in the cylindrical portion of the valve, means to introduce airto the cylindrical portion and fuel to the fuel con-' dnit respectivelyand to permit axial movement of thetwo parts together and a spreader onthe disk close to and above the fuel conduit.

6. In a carbureter the combination of, an air valve comprising a hollowstem and a flattened or extended head the underside.

thereof being conical and taperingtoward the stem, a fuel conduitarranged in the hollow stem, means to admit air to the hollow stem andfuel to the fuel conduit respectively, a disk adjustably secured'to theflattened hea d and arranged above the fuel out let, a casingsurroundingthe air valve providing a valve-seating for the conical portion of thevalve, said casing being opened to the atmosphere by movement of thevalve.

lin testimony whereof I have signed my name to this specification inthe"prescnce of two subscribing witnesses. l
